Each phase bridge of the three-phase four-bridge arm and the fourth bridge arm constitute a full-bridge inverter. The input filter capacitor required by the three-phase four-bridge inverter of the same power level is much smaller than that of the three-phase half-bridge inverter. Therefore, compared with the three-phase half-bridge inverter, the three-phase four-leg full-bridge inverter has the advantages of small size, light weight and low cost, so it has good application value. This product is a zero-sequence current injection PWM control, which can realize the decoupling control of the three-phase four-bridge inverter, and the control method is simple, easy to understand and realize. Compared with the conventional sine wave modulation method, the utilization rate of the DC bus voltage has been improved, and it has good performance with unbalanced loads. The three-phase four-bridge inverter is mainly used for UPS, intermediate frequency inverter and aviation airborne variable-speed constant-frequency power generation system that supplies power to three-phase asymmetric loads. The three-phase four-bridge inverter carries SPWM wave frequency of 16.000KHz. Each phase of the circuit is independently controlled, and there is no coupling relationship between them. The three-phase four-bridge inverter can be decomposed into three independent single-phase full-bridge inverters. Each inverter outputs The switching mode of the three-phase four-bridge-arm inverter with a voltage phase difference of 120° is composed of a three-phase half-bridge inverter and a common bridge arm composed of CN10 and CN11. The three-phase four-bridge arm outputs three-phase four-wire, including line voltage, phase voltage and neutral line; the neutral line can output high power, and can resist unbalanced load in three-phase.
• Pure full high frequency inverter conversion circuit
• Automatic switching between local mode/485 communication mode, 485 communication priority
• The output voltage, current and power can be adjusted from 0, constant and adjustable, 485 touch screen operation
• With output voltage constant voltage and bus current constant current, it is completely comparable to the power frequency machine when starting the inductive load
• The soft start of the motor can be realized when it is turned on. In the constant current output mode, the output waveform is always pure sine wave
• In the case of not using 485 communication, the voltage is set to 380V output
• Support external 485 communication voltage, current, power display and adjustment
• The board has switch control output function, default power on
